Since the previous status report in November of 1970, there has been little progress made in the actual implementation of domestic satellite television systems, because comprehensive technical specifications had not been provided by the three broadcast networks, ABC, NBC, and CBS. When the requirements were submitted to the interested vendors, PBS (Public Broadcasting Service) requirements were excluded due to the uncertainties of the free or reduced rates issue. This issue still has not been resolved. Nevertheless, PBS, CPB (Corporation for Public Broadcasting), and NPR (National Public Radio) have filed comments supportive of the FCC (Federal Communications Commission) position, especially with regard to the system objectives. They also filed recommendations for future requirements, particularly for the use of spot beams, frequency bands at 2.5, 7, and 12 GHz, and link parameters for dual service for more economical use of the satellite system. Currently joint requirements are being developed with the major networks, specifically in regard to technical specifications and the number of satellite channels and ground terminals. At this time the major obstacles for PBS participation in the system have been removed. (MC)
